This poignant piece of paper charting the fate of the 19 Dambusters' crews highlights the cruel and random nature of the famous World War Two raid.
Flight Sergeant Leonard Sumpter got hold of a typed list of all the RAF bombers involved in Operation Chastise and ticked off the unfortunate crews which didn't make it back.
Of the 19 Lancaster bombers, eight were shot down resulting in the deaths of 53 airmen. Two others had to return to England after developing faults.
The crew list has now emerged for sale for £800.
